Explain Tay-Sachs disease. Imagine you are a genetic counselor working with a couple who have just had a child who is suffering from Tay-Sachs disease.
Neither parent has been tested for Tay-Sachs disease nor have there been any previous cases of Tay-Sachs in either family.
Explain Tay-Sachs disease and provide a discussion of the information you would share with the couple about Tay-Sachs and possible implications for future children.
